SENSOR SYSTEM FOR DETECTING ANALYTES IN TEAR FLUID

摘要

A sensor system for the detection of endogenous or exogenous substances in lachrymal fluid is described, which comprises a substance-specific detection system contained in a contact lens. This detection system may be contained in hollow cavities, microchambers or microtubes, or even in microchambers formed from semi-permeable films, which are embedded into a hydrogel layer of the contact lens.
